Key result
Heart rate during the apneic period of periodic breathing at high altitude was significantly lower than during the ventilatory period (56.0 vs 74.6 beats/min).
Why the study?
Does hypoxic chemosensitivity affect heart rate depression during sleep apnea at high altitude?
Observational (n=7)
Does hypoxic chemosensitivity affect heart rate depression during sleep apnea at high altitude?
Absolute Event Rate: 56% vs 74.6%
Heart rate depression during sleep apnea at high altitude correlates with oxygen desaturation and is modulated by individual hypoxic chemosensitivity.

May link HR slowing to HVR in high-altitude PB; hypothesis-generating and should not change practice.
Masuyama et al. (1990) conducted an observational in Sleep apnea and periodic breathing (n=7). Apneic period during periodic breathing vs. Ventilatory period was evaluated on Heart rate during the apneic period versus the ventilatory period of periodic breathing. Heart rate during the apneic period of periodic breathing at high altitude was significantly lower than during the ventilatory period (56.0 vs 74.6 beats/min).
